It has been more than 10 days now since Sony released much awaited Android 4.1.2 Jelly Bean 6.2.B.0.200 firmware for Xperia S LT26i, Xperia SL LT26ii and Xperia Acro S LT26w. The then users are asking how to root Jelly Bean 6.2.B.0.200 firmware ROM, well now we have a solution for that query, Cheers 🙂

We assume your Xperia S LT26i and Xperia SL LT26ii is on official android 4.1.2 Jelly Bean 6.2.B.0.200 firmware. If you have not got the official notification yet for the Jelly Bean 6.2.B.0.200 firmware update then you can install it manually from the given below link.

# Download above files, create a folder named “Fastboot” and place all above recovery files in it and the files from fasboot.zip
# Switch off your phone now. Connect phone to PC.
# Pressing “Volume down” button, enter into “fastboot mode”. Now open the folder “Fastboot”.
# Now Press “shift+rightclick” and now choose option “open cmd widnow here”.

Follow the given below command by DooMLoRD.

type: fastboot flash boot S_DooMLoRD_AdvStkKernel_FW-200_v2.elf

If successfully done, now you have a rooted Xperia S on original android 4.1.2 Jelly Bean 6.2.B.0.200 firmware ROM.

“fastboot flash boot S_DooMLoRD_AdvStkKernel_FW-200_v2.elf”……………… I tried this command and found it to be not executing…….. it showed some errors..

then i found it is written “v2″ in the command, so i changed it to be ” v1″ in accordance with the file name “S_DooMLoRD_AdvStkKernel_FW-200_v1.elf”…… then in some seconds the command window stoped running and stated “finished totel time:2.635s”……

my phone is XSl and it is running the first official JB update…. bootloader was unlocked….

Don’t use this shit, it fucked my phone, it became unable to charge using dock, & didn’t read SD card, & didn’t start charging at all need to be shutdown to start charging.
it fucked my phone xperia acro s
